Welcome to the Diesel Stop.
Your going to get lots of different opinions from lots of different members running lots of different tunes. In my opinion Like anything else, proper use and respect shouldn't have a noticeable reduction in the lifespan of your engine. Make sure you include gauges in your budget, so you can monitor things.

Don't worry about that - there are several different techniques to greatly minimize or eliminate that. I used a vacuum cleaner next to my drill bit. When I got through, I used a magnet in the hole and tapped all around - nothing made it into the hole using the vacuum. Plus, think how many hundreds of thousands of us that have done this and had no problems.

I am sure the custom tunes from Caryt are great - all of his products are. I don't have any personal experience with them, but I do with the DP-Tuner. That is the best thing I have ever done to my truck. You will absolutely hate yourself for waiting this long to do it.

My opinion, backed by 29 years of automotive engineering experience, is that yes, this will hurt your engine's longevity. How much it will hurt it is an open question. That depends on many factors. One of the most important factors is how you drive it.

Well my old '95 has now got 280k miles on it, chiped day one 45k miles pulling a 35' 5th wheel then had stage 2's for about 100k miles...now stage 1's for the new owner last 40k. Getting 18-19 hy 16 town.

I would chip it. But, if you drive it like a hot rod, then I imagine you will shorten the life. I was hesitant to chip mine and waited until after the warranty was done. I think that was at about 65k miles or so. I drive mine like a grandpa and then zip around in my old BMW.
